Application filed May 1, 1914. SeriaINo. 835,653. 7

' from collapsing when empty, and the object is to provide wooden stave silos with certain adjustable and economical braces which are easily and quickly applied and which will be highly eflicient in preventing the blowing down or collapsing of the silos when empty and which can be easily and quickly removed as the silos are being, filled.

Other objects and advantages will be fully explained in the following description and the invention will be more particularly pointed out in the claims.

Reference is had to the accompanying drawings which form a part of this application.

Figure 1 is a horizontal section of a silo, equipped with the improved braces. Fig. 2 is a horizontal section, on an enlarged scale, showing in detail one manner of adjusting the main circular brace. Fig. 3 is a broken vertical section taken along the line mm of Fig. 2. Fig. i is a broken vertical section, showing one way of attaching the sectional braces to the main brace. Fig. 5 is a broken plan view, showing another way of attaching the sectional braces to the main brace. Fig. 6 is a broken vertical section, showing one manner of mounting the main brace and the guy rods or cables. Fig. 7 is a broken vertical section, showing a variation in the main brace and the manner of mounting the same.

Similar characters of reference are used to indicate the same parts throughout the several views.

Sections of a silo are shown to illustrate the improvements applied to the silo. The silo is provided with a base 1 and vertical wooden staves 2 which are usually joined by tongue and groove joints 3, but the joints may be made by flat faces cut to form a circle when put together. The main brace 4.- is a continuous brace which may be made of a single piece of L-shaped angle iron or as many pieces as may be desirable or convenient. The ends of the brace 4 are connected by lapping the same on each other and boltmg the same together. It is apparent that channel iron can be used instead of the L shaped iron. The lapped portions of the angle iron are to be provided Witha plurality of holes 5 so that the circle of the mam brace may be varied to adapt the same to different sizes of the inner walls of silos. The ends of the brace 1 can be lapped on each other and the holes in the two ends can be made to register with each other so that the bolts 12 can be inserted to secure the ends together. The brace 4 can be mounted on the inner wall of the silo at as many points as may be necessary and the braces can be.

mounted as the ensilage is used or removed so that a person can stand on the ensilage and mount the brace and the brace can be removed as the silo is being filled. When ensilage is filled in up to a brace, the brace can be removed and no laddersof any kind will be necessary. The brace 4: may be mounted with brackets 6, such as shown in Figs. 1 and 6, or with such devices as are shown in Fig. 7. The main brace 4 can be braced with a number of sectional or cross braces 7 and 8. Holes 5 may be made in the base flange of the brace 4: so that the bent ends of the braces 7 and 8 can be inserted, as shown in Fig. 41, or plates 9 may be attached to the base of brace 4c and the braces 7 and 8 caught in the plates 9. The brace rods 7 and 8 are provided with turnbuckles 10 for adapting braces 7 and 8 to the brace 4;. Guy wires or rods 11 may be caught in the attaching U-bolts 11, as shown in Fig. 6.

The adjustment of the circular brace is made preferably only at the front of the silo. The vertical flanges of the lapping portions of the brace 1 are cut away and the ends lapped on each other and secured together by bolts 12. The ends of the brace are made adjustable by providing a plurality of holes. The parts of the brace which lap on each other may be further braced against inward displacement by lugs 14:, as shown in Figs. 2 and 3. The extreme ends 15 of the brace 41 may extend along beside the flange 16 of the brace 4. One of the braces 4% can be permanently attached to the interior of the silo at the upper end. Below the upper end, the braces 4 are temporarily attached to the interior of the silo while empty. The brackets or clips 6 which hold the brace a in place are removed with the brace at, and in order to retain the U-bgilts 17 in P plates 18 re rat n the pla e f, t e brackets 6 and secured on the ends of the U-bolts 17 by nuts 19. The term of the U-bolts 17 is necessary to hold' the band or lt 20 nd he guy wire 11 in P ace The bands or belts 20 may be held in place by simple U-bolts 21, such as are shown in Fig; 7, and by plates 22, where there is no brace 4 to utilize the form of U-bolt 17. The plates 18 might be madeconti'nuous to form in;- teri'or 'band' which would serye as a brace combination with the sectional or cross braces 7 and 8,

Various: changes may be made without departing from: my intentionand there may be any suitable number of braces togetherwith the cross braces wh ch are used as tensiontioned brace is increased."

2. The combination with a silo of a removable rigid brace therefor comprising an Jinner ringlike brace member adapted to be ti'oned brace is increased, said ringlike brace member formed in segmental sections, and means for securing the ends of the sections together adapted to prevent slipping.

3. The combination with a silo of a removable rigid brace therefor comprising an inner ringlike brace member adapted to be adjusted to its length, and cordli-ke braces connected to the first mentioned brace at their ends whereby the rigidity of first mentioned; brace is increased, said ringlike brace member being formed in segmental sections,

and means "for securing the ends of the sec ti'ons' together adapted to prevent slipping, said cordli'iie braces subtending a segment o fithe first mentioned brace which includes a joint.

testimony whereof, I set my hand in the presence of two Witnesses, this 27thof April", 1914:.
